Part D Total Premium: The Part D Total Premium is the sum of the Basic and Supplemental Premiums. Note: the Part D Total Premium is net of any Part A/B rebates applied to "buy down" the drug premium for Medicare Advantage plans; for some plans the total premium may be lower than the sum of the basic and supplemental premiums due to negative basic or supplemental premiums.

Coverage gap ("donut hole"). This means there's a temporary limit on what the drug plan will cover for drugs. (Unless you get the low-income subsidy) Once you reach the coverage gap in 2014, you will pay 47.5% of the plan's cost for covered brand-name prescription drugs. You get these savings if you buy your prescriptions at a pharmacy or order them through the mail.

Additional gap coverage levels are determined separately for formulary generic and brand products and are described as follows:

All: 100% of formulary drugs are covered through the gap

Many: 65% to 100% of formulary drugs are covered through the gap

Some: 10% to 65 % of formulary drugs are covered through the gap

Few: 0% to 10% of formulary drugs are covered through the gap (and must also be >15 "brand" products covered through the gap)

No Gap Coverage: 0% of formulary drugs are covered through the gap (or 15 "brand" products covered through the gap)

All Formulary Drugs: cover 100% of “generic” and 100% of “brand” products (either by covering all formulary drug products in the gap or by having no initial coverage limit)

Maximum Out-of-Pocket (MOOP) limit on enrollee spending that includes costs for all in-network Part A and Part B Services. NOT Part D - prescription drugs. N/A is defined as Not Applicable
